On: NASA to launch space observatory that will map 450M galaxies

The Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Survey has recorded more than one billion galaxies.

But there are many more galaxies in the observable universe … somewhere between 2 and 20 trillion

A bit less officially, need to remove one zero [1]

There are more recent estimates going from 6-20 trillion now: https://bigthink.com/starts-with-a-bang/galaxies-in-universe...

That article is going beyond the observable universe, other comments were talking about within it.

What makes you think that? I quote:

Yeah, the scale of it is absolutely mind-blowing
